SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing an
environmental assessment (EA) and finding of no significant impact
(FONSI) related to a request for alternate
[[Page 13916]]
disposal, exemptions, and associated license amendment for the
disposition of waste containing byproduct material and special nuclear
material (SNM) from the Westinghouse Electric Company, LLC's (WEC)
Columbia Fuel Fabrication Facility (CFFF) in Hopkins, South Carolina,
under License Number SNM-1107. The material will be transported to and
disposed consistent with a previously granted exemption granted to WEC
and the US Ecology, Inc. (USEI) disposal facility, located near Grand
View, Idaho, which is a Subtitle C Resource Conservation and Recovery
Act (RCRA) hazardous waste disposal facility permitted by the State of
Idaho to receive low-level radioactive waste. The NRC is also
considering the related action of approving a corresponding exemption
to USEI. Approval of the alternate disposal request from WEC and the
exemptions requested by WEC and USEI would allow WEC to transfer the
specific waste from CFFF for disposal at USEI.
DATES: The EA and FONSI referenced in this document are available on

SUPPLEMENTARY INFORMATION:
I. Introduction
By letter dated February 8, 2021, WEC requested an exemption and
associated license amendment to License SNM-1107, issued for the
operation of CFFF located in Hopkins, South Carolina pursuant to
section 20.2002 of title 10 of the Code of Federal Regulations (10
CFR). By letter dated February 25, 2021, USEI incorporated the WEC
application in its request for a corresponding exemption. The requests
are for NRC authorization for an alternate disposal of specified NRC-
licensed byproduct and SNM from the CFFF. As required by 10 CFR 51.21,
the NRC conducted an EA. Based on the results of the EA that follows,
the NRC has determined that pursuant to 10 CFR 51.31, preparation of an
environmental impact statement for the exemption request is not
required and pursuant to 10 CFR 51.32, issuance of a FONSI is
appropriate.
Westinghouse had previously requested and received an exemption and
license amendment, dated December 9, 2020 to, among other things,
transfer approximately 1428 m\3\ (50,400 ft\3\) of solid contaminated
Calcium Fluoride (CaF2) sludge to the USEI RCRA Subtitle C
hazardous waste disposal facility near Grand View, Idaho that was
dredged from the Calcium Fluoride Lagoons and subsequently placed in a
storage pile. USEI was granted a corresponding exemption to receive and
dispose of this material on December 9, 2020.
After Westinghouse moved the CaF2 sludge dredged from
the Calcium Fluoride Lagoons, WEC discovered that the actual volume was
less than the 1428 m\3\ (50,400 ft\3\) previously estimated. The actual
volume was 694 m\3\ (24,500 ft\3\). In its subsequent application, WEC
stated its intent to use other, similar CaF2 material in
order to aggregate the waste for disposal as requested and approved in
the December 9, 2020 authorization. In its February 8, 2021 letter, WEC
requested an exemption and license amendment to dispose of 733 m\3\
(25,900 ft\3\) of similar CaF2 from another source, the
``Operations'' pile. The total amount of CaF2 material (from
the previous approval and that under consideration here) would not
exceed the previously approved volume of 1428 m\3\ (50,400 ft\3\), nor
would it exceed the parameters of the radiological characterization
that formed the basis of the NRC staff's previous approvals, as
documented in the Safety Evaluation Report (SER).
II. Environmental Assessment
Description of the Proposed Action
WEC and USEI requested NRC approval for a 10 CFR 20.2002 alternate
disposal request, exemptions to 10 CFR part 70.3 and 10 CFR 30.3, and a
conforming WEC license amendment to allow WEC to transfer specific
waste from CFFF for disposal at the USEI disposal facility.
Waste being considered in this request includes approximately 708
m\3\ (25,900 ft\3\) of previously dredged CaF2 sludge being
stored on the operations pile. WEC proposes to mix this material with
other waste and Portland cement to stabilize the material for shipping.
WEC proposes to transport this aggregated waste stream to USEI using a
combination of trucks and railcars. The combined volume of
CaF2 sludge disposed of under the December 9, 2020
authorization and that under consideration here would not exceed the
previously approved volume of 1,428 m\3\ (50,400 ft\3\) of
CaF2.
The waste streams would be transported from CFFF in South Carolina
to the USEI facility, Grand View, Idaho in the Owyhee Desert. The USEI
facility is an RCRA Subtitle C hazardous waste disposal facility
permitted by the State of Idaho. The USEI site has both natural and
engineered features that limit the transport of radioactive material.
The natural features include a low precipitation rate [i.e., 18.4 cm/
year (7.4 in./year)] and a long vertical distance to groundwater (i.e.,
61-meter (203-ft) thick on average unsaturated zone below the disposal
zone). The engineered features include an engineered cover, liners, and
leachate monitoring systems. Because the USEI facility is not licensed
by the NRC, this proposed action requires the NRC to exempt USEI from
the Atomic Energy Act of 1954, and NRC licensing requirements with
respect to USEI's requested receipt and disposal of this material.
Need for the Proposed Action
The need for the proposed action is to authorize a safe and
appropriate method of disposal for the subject waste material generated
during day-to-day activities and currently being stored at
[[Page 13917]]
the CFFF. Specifically, the East Lagoon is in the process of being
closed in accordance with a consent agreement and regulations set by
the South Carolina Department of Health and Environmental Control
(SCDHEC). Thus, material associated with the East Lagoon must be
removed from the site in order to comply with regulatory requirements.
As was the case with the May 8, 2020 request, the subject
CaF2 material and Portland cement would be used to stabilize
this material for transport and disposal. The proposed alternate
disposal would also conserve low-level radioactive waste disposal
capacity at licensed low-level radioactive disposal sites while
ensuring that the material being considered is disposed of safely in a
regulated facility.
Environmental Impacts of the Proposed Action
The NRC staff reviewed the information provided by WEC to support
their 10 CFR 20.2002 alternate disposal request and for the specific
exemptions from 10 CFR 30.3 and 10 CFR 70.3 in order to dispose of the
CaF2 waste. Under the 10 CFR 20.2002 criteria, a licensee
may seek NRC authorization to dispose of licensed material using
procedures not otherwise authorized by NRC regulations. The licensee's
supporting analysis must show that the radiological doses arising from
the proposed 10 CFR 20.2002 disposal will be as low as reasonably
achievable and within the 10 CFR part 20 dose limits.
WEC previously performed a radiological assessment in consultation
with USEI. Based on this assessment, WEC concluded that potential doses
to members of the public, including transportation workers and USEI
workers involved in processing and disposing of the waste upon its
arrival at USEI, are less than 1 mrem/y, well within the ``few mrem''
criteria that the NRC established (see NUREG-1757, Volume 1, Revision
2).
As documented in the SER, the NRC staff reviewed scenarios and
related input parameters considered by WEC and USEI and found that they
are appropriate for the scenarios considered. The NRC staff also
reviewed the projected doses from the post-closure and intruder
scenarios at USEI and found them acceptable. NRC staff did note that
the inadvertent intruder construction scenario had potential doses that
were larger than the other inadvertent intruder scenarios evaluated,
but the NRC does not consider this scenario to be feasible due to the
configuration of the disposal cells and USEI's waste disposal
practices. NRC staff also notes that the proposed disposals are also
subject to regulation under RCRA. These conclusions are consistent with
the NRC's findings in its SER for the previous request, reflective of
the similar radiological characteristics of the material from the
operations pile and that described in the May 8, 2020 request.
Based upon its the previously noted evaluation and its assessment
of the potential impacts of the proposed action, in addition to
focusing on the potential radiological impacts as previously discussed,
this EA next considers potential environmental impacts from non-
radiological materials. With regard to potential non-radiological
impacts, the NRC staff concludes that approval of the proposed request
to dispose of material with small amounts of radioactive material would
not have significant environmental impacts, including effects on non-
radiological effluents, air quality, or noise. In addition, approval of
the proposed action will not significantly increase the probability or
consequences of accidents as well as occupational and public radiation
exposure because of the quantities and forms of material involved, as
further evaluated in the NRC's SER.
Therefore, due to the very small amounts of radioactive material
involved, the evaluation noted earlier, and the NRC staff's analysis in
the SER and its SER for the May 8, 2020 request, the NRC staff finds
that the environmental impacts of the proposed action are not
significant.
Environmental Impacts of the Alternatives to the Proposed Action
As an alternative to the proposed action, the NRC staff considered
the no-action alternative in which the NRC staff would deny the
disposal request. Denial of the request would require WEC to find
another disposal pathway for this material, and would ultimately only
change the location of the disposal site. All other factors would
remain the same or similar. Therefore, the no-action alternative was
not further considered. NRC staff also notes that pursuing the no-
action alternative would result in the licensee potentially violating
the SCDHEC requirements to remove the material from the East Lagoon so
that it can be remediated while it identifies another disposal option.
III. Finding of No Significant Impact
The proposed action consists of NRC approval of (a) WEC's and
USEI's alternate disposal requests under 10 CFR 20.2002, (b) WEC and
USEI's exemption request under 10 CFR 30.11(a) and 10 CFR 70.11(a), and
(c) the issuance of a conforming license amendment to WEC. Based on
this EA, the NRC finds that there are no significant environmental
impacts from the proposed action. Therefore, the NRC has determined,
pursuant to 10 CFR 51.31, that preparation of an environmental impact
statement is not required for the proposed action and a FONSI is
appropriate.
